I'm having trouble doing this, dumb computer, but I've tried to draw
a Wet Mill Thickness Gauge to show those of you who
don't have one, what it looks like.
It looks like a metal credit card with notches on all four sides.
The notches measure the thickness of the wet finish
from one up to 80 mills thick.
The blue line is the table top that the corners of the gauge set on.
The red line is the finish itself.
In this example, the finish is 3 mils thick.
